OK, Got it working!!!
This was probably the most simple yet difficult to find fix - mostly due to my error!!!
Of course, if Joomla had their docs sorted for 2.5 this would have been straight forward. Anyway...
Here's the fix...
Contrary to that in J1.5 syntax for calling the login function like
In J2.5 you
MUST USEonUserLogin($user, $options)
That's it!
Follow the
original post
with this small change (should be reflected there by the time you read this)...
Many thanks @admin for your time looking into this!!!
